8. The vortex solid-liquid separation device according to claim 1, wherein a dry sludge delivery pump is arranged at the outlet of the separator, and a high-pressure cleaning pump and a silent air compressor are further arranged on the separator.
9. The vortex solid-liquid separation device according to claim 8, wherein a PLC electric control system is arranged on the inner side wall of the box body and used for controlling the electric work of the mud pump, the medicine pump, the separator, the high-pressure cleaning pump, the silent air compressor, the dry sludge delivery pump, the first flocculator and the second flocculator.
10. A sludge solid-liquid separation method is characterized by comprising the following steps:
the sewage is fully automatically controlled to enter a sewage pipeline in the vortex solid-liquid separation device from a sewage inlet;
adding a flocculating agent into a first flocculator, enabling sewage in a sewage pipeline to pass through the first flocculator, mixing the flocculating agent with the sewage through the first flocculator, and then entering a concentration device for flocculating and precipitating;
controlling the supernatant outlet to be opened so that the supernatant liquid in the concentrating device is discharged;
controlling the sludge pump to start working, so that the sludge flocculated and precipitated at the bottom of the concentration device enters a sludge pipeline;
adding a secondary flocculating agent into the second flocculator, stirring and mixing the sludge and the secondary flocculating agent through the second flocculator, and conveying the mixture to a separator;
squeezing and separating by the separator to obtain dewatered mud cake and liquid clear water, and discharging.
